Application filed April 3, 1906. Serial No. 309,584.

(To all whom, it may concern:

Be it known that I, CLARENCE E. BOWER, la citizen of the United States,vresiding at Denver, in the county of Denver and State of Colorado, haveinvented certain new and useful Improvements in Ealing-Presses, of whichthe following is a specification.

My invention relates to baling resses and more especially to that classof t e half-cycle type in which a reversible sweep is connected toimpart forward movement to the plunger and to effect the automaticrelease of such plunger to permit it to be returned to position to makeits next power stroke, and my object is to produce a baling press ofthis character having a comparatively long power stroke, and embodyingfeatures of construction whereby any tendency of the plunger to stick inthe baling case is overcome.

Other objects of the invention will hereinafter appear and it consistsin certain novel and peculiar features of construction and organizationas hereinafter described and claimed, and in order that it may be fullyunderstood reference is to be had to the accompanying drawings, inwhich- Figure 1,is a top plan view of a baling press embodying myinvention. Fig. 2, is a side view of the same. Fig. 3, is a horizontalsection of the press on the line III-III of Fig. 4. Fig. 4, is a frontview of the press as shown in Fig. 1. Fig. 5 is a vertical section takenon the dotted line V of Fig. 1. Fig. 6, is a detail pers ective view ofa rock-lever forming part of t e machine. y

In the said drawings, 1 indicates the baling case, 2 the feed opening,and 3 the feedopening hopper of a baling press.

4 indicates corner irons-angle irons by preference,-extending forwardfrom the press and connected at their front ends by top and bottom crossbars 5` and 6 respectively. The forwardly projecting frame constitutedby these angle irons may be cased in or not as desired, the drawingssimply showing the angle irons braced from lateral movement as at 7, oneset of the braces not appearing.

8 indicates the power shaft having its ends 9 journaled in cross bars 5and 6, and provided with a `trip lever, comprising the oppositelyprojecting arms 10, having depending abutments 11, at their outer ends.The power shaft is furthermore provided with a channeled arm 12,disposed at right angles to the trip lever and above the sameandjlfitted in"and boltedw'to said channeled arm 12 is a sweep or horselever 13. H"

14 indicates a lever pivoted upon the power shaft below the trip leverand in the plane of abutments 11 of the latter and of such length thatits independent movement will be limited by said abutments to less thanone hundred and eighty degrees. In order that this lever shall maintainits proper relation to the trip lever its hub portion 15 is extended soas to rest upon the cross bar 6, the lever being preferably cast withstrengthening ribs 16 projecting from opposite sides of the extended hubportion, and at one end the lever is provided with a boss 17, providedwith avertical opening 18 to receive a pivot bolt 19, said pivot boltbeing connected by links 20 above and below the latter to a pivot bolt21, extending vertically through a casting 22, mounted on the end of theplunger beam 23, the bolt 21 forming a journal for an anti-frictionroller 24 which is adapted at times to engage the abutmcnts of the triplever. At the front end of the plunger beam is secured in the usual orany preferred manner, a reci rocatory plunger 25 for operation in the baing case in a wellknown manner,

and said plunger is connected by a retractile spring 26 to a fixedportion of the framework, which spring is for the purpose of effectingthe recoil of the plunger in the usual manner.

In the practical operation of this machine, the draft animal, not shown,is hitched to the sweep and driven in the direction indicated by thefeathered arrow Fig. 1, when the parts are disposed as shown in saidfigure, the baling chamber having of course received a charge ofmaterial to be baled. As the sweep is moved in the direction indicated,the abutments of the trip lever by pressure in opposite directions onthe pivoted lever 14 cause the latter to turn in the same direction andtherefore compel the plunger beam to move the plunger forward. As thisaction takes place the links 20 move relatively in the oppositedirection, as indicated by the arrow a Fig. 1, so that the roller 24 ofthe plunger beam comes into engagement with the contiguous end of thetrip lever when the latter has made about half its stroke, as indicatedin dotted lines Fig. 1, at which time and until the completion of thestroke, the links are depended upon to hold said roller in the path ofmovement of the trip lever, as the tendency of the former during theintermediate portion of its movement is to swing outward beyond IOOcourse being defeated becausev it is linked to the path of the triplever, this tendency of the power shaft by the lever 14 and links.

Shortly after the trip lever has passed the half-way point in itstravel, it imposes a direct endwise pressure upon the plunger beam asshown clearly in dotted lines Fig. 3. Eventually, that is, shortlybefore the trip lever has traveled a full half circle, the pivotal pointof the plunger beam with the plunger, and the axis of its roller and ofthe engaged abutment arebrought into longitudinal alinement, thecontinued movement causing the lever to break such alinement by drawinothe roller inward of the vertical plane of said abutment and the pivotalpoint of the plunger beam in order that the retractive tendency of thespring 26 may effect the withdrawal action of the plunger. In thisaction the lever 14 and the plunger move from the position shown indotted to the position shown in full lines Fig. 3, and shortly afterthis recoil takes place the sweep attains the position shown by the headof the arrow b, Fig. 3, though it will be understood that the parts maybe so arranged that the movement of the sweep may be increased ordiminished if desired. In this connection it will be noticed byreference to the dotted position of the parts in Fig. 3, that if theplunger should stick so firmly in the baling case that the spring couldnot withdraw it, that the continued movement of the trip lever wouldpositively effect such release because it would exert a direct pull uponthe plunger through the medium of the lever 14, links 20 and the plungerbeam 23.

Following each recoil of the plunger the draft animal is turned so as totravel back to the point from which he started, and in such movement thetrip lever is turned in the opposite direction to that described, andeffects the next power stroke of the plunger, the opposite end of thetrip lever in this reverse movement coming into direct engagement withthe anti-friction roller ofthe plunger beam. It will thus be seen thatthe ends of the trip lever alternately apply direct pressure on saidroller.

From the above description it will be apparent that I have produced abaling press embodying the features of advantage enumerated as desirablein the statement of invention, and I wish it to be understood that I donot desire to be limited to the exact details of construction shown anddescribed for obvious modifications may occur to a person skilled in theart.

I-Iaving thus described the invention what I claim as new and desire tosecure by Letters Patent is l. In a baling press, a power shaft having apair of oppositely projecting trip arms having vertical abutments, arock-lever journaled on said power shaft in the horizontal plane of theabutments and in a vertical plane which intersects the vertical plane ofthe trip arms, a plunger beam, and a link pivotally connecting theplunger beam with one end of the rock-lever so that the rear end of saidbeam shall just prior to thel latter part of the compression stroke bedirectly engaged by one or the other of the abutments.

2. In a baling press, a power shaft having a pair of oppositelyprojecting trip arms having vertical abutments, a rock-lever journaledon said power shaft in the horizontal plane of the abutments and in avertical plane which intersects the vertical plane of the trip arms, aplunger beam in the horizontal plane of the trip arm abutments, a rollerjournaled at the end of said beam, a link pivotally connecting therock-lever with the beam, and means for operatingV the power shaft andcausing the latter to swing said link in a relatively opposite directionto that of the trip lever until the contiguous abutment of the latter ispressing against the roller of theV plunger beam. v

3. A baling press, comprising a suitable frame, a vertical power shaftjournaled therein and provided with opposite projecting trip arms havingdepending abutments, a sweep rigid with the power shaft, a lever pivotedon the power shaft between the abutments of the trip arms and extendingat an angle to the latter and occupying the path of motion of saidabutments, a reeiprocatory plunger in the baling chamber of theframework, a spring to withdraw the same, a plunger beam pivotedto theplunger, and links pivotally connecting the plunger beam with saidlever.

In testimony whereof I affix my signature, in the presence of twowitnesses.
